Creating New Genes, or Enhancing Underlieng Genes

So I was thinking, dont be scared, all these new morphs that do not really occur in nature are genes the snake already has? correct? So when the breeders refine, refine, and refine, untill they get something crazy, like lucys, are they taking the genes that are there, but very underlieing? I dont know if im even making sense, but if we cross and cross genes, are we technically making new genes that get passed on? Or are the genes that are they just coming out in full force?

It's just combining genes that are already there in new ways...as well as giving genes a chance to be expressed that don't normally get a chance with random, wild selection.

All most morphs are is a mutation. Mutations don't create new genes, they corrupt an old one (mutations are copying mistakes in DNA)

If the gene is there, it might get expressed in the wild, but the snake wouldn't survive long.
A all white snake wouldn't be able to hunt well, nor would it be much else than a easy target. But if one hatches from a egg in a CH facility, it would be snapped up fast.
We just keep the ones that express that gene, or those related to it.
